What Is Overfitting? Why Can More Finely Tuned Parameters Make a Strategy More Fragile?
In cryptocurrency trading, some strategies show increasingly high historical returns and increasingly attractive backtest curves after repeated parameter adjustments. However, once they enter live markets, their performance can quickly deteriorate. A common reason behind this is overfitting.
First, what is overfitting?
Overfitting occurs when a strategy adapts too closely to specific fluctuations and chance patterns in historical data, leading it to perform well in the past but lack the ability to adapt to

IT Home reports that a drone pilot says Tesla’s Texas Gigafactory has added a night shift, potentially doubling capacity, and that the delivery area is packed with gold Cybercabs. Tesla has yet to confirm the changes or what the vehicles are for.
The information chain is a little backward right now: aerial footage shows the night shift and the lot packed with cars, but the company hasn’t said a word, so the market can only treat the pilot’s observations as a clue for now.

Market Update: AAPL (Apple Inc.) – Technical Rebound Meets Resistance
$AAPL
Apple Inc. ($AAPL) is currently showing a decisive bullish recovery on the intraday charts, rebounding sharply from recent lows. The stock has reclaimed significant ground, currently trading at $349.60, representing a notable +5.39% move on the day. However, while the intraday momentum is strong, the broader structure suggests the asset is entering a critical resistance zone following a sharp selloff from the $354.47 high.
Technical Structure & Price Action.
Looking at the 15-minute chart, the price action is characte

$XCRCL Currently at 75.4, 24H +0.13% (72.79–78.2). 1H is weak: RSI 27.27, with the current price below the 1H EMA20 at 75.64; 4H is strong: RSI 59.48, with the current price above the 4H EMA20 at 74.97. The 1H volume ratio is 0.0012, indicating very low participation. If price holds above the 78.2 resistance level, watch for continuation; if it breaks below the 72.79 support level, the short-term outlook may weaken. In the next review, check whether price can hold above 78.2 and recover after losing 72.79; the volume ratio is 0.0012x, so a break beyond these levels needs confirmation from part

What Is the MACD Indicator? How Can You Use Crossovers and the Histogram to Track Changes in Trend Momentum?
In cryptocurrency trading, short-term price fluctuations can easily cloud your judgment. MACD is a common trend-following indicator that helps traders analyze trend direction and momentum by observing crossovers between two lines and changes in the histogram. However, it cannot accurately predict every price rise or fall, and it is not suitable for use on its own without considering market conditions.
First, what is MACD?
MACD stands for Moving Average Convergence Divergence, and its co

Machi Big Brother is making a killing again!
He’s not only going long but also adding to his position, increasing from over 2,000 contracts to nearly 6,700 with 25x leverage. His latest average entry price is 2366, and unrealized gains have topped $460k, but his liquidation price has also been pushed up to 2391.
Big Brother is charging ahead with total confidence, but I’m actually not very optimistic about this move in the short term. I recommend positioning for shorts near 2450.
The reason is simple:
This rebound after the election results came in looks more like a short squeeze following the
